Alarm Removal
Refer to the Alarm Tamper Resist Feature section for
removal instructions.
To remove the alarm from the mounting plate, rotate the
alarm in the direction of the "OFF" arrow on the cover.
WARNING: Do not attempt to open the alarm for any reason!
Battery
A Lithium-ion battery, permanently sealed inside the alarm,
powers this unit. No battery installation or replacement is
necessary for the life of the alarm.
This alarm has a low battery monitor circuit which will
cause the alarm to "chirp" approximately every 40-45
seconds for a minimum of thirty (30) days at the end of the
life of the alarm. Replace the alarm when this condition
occurs.
Deactivation
WARNING: Do not deactivate the alarm until the end of the alarm life,
when a "chirp" is heard every 40-45 seconds. Once the alarm is
deactivated, the battery will be drained and the alarm will no longer
function.
WARNING: Once the alarm has been deactivated, it cannot be reactivated
and it cannot be reattached onto the mounting plate!
To deactivate the alarm remove the alarm from the
mounting plate and locate the black square on the back
label.
Puncture the black square area with a screwdriver or
similar tool then slide the exposed piece towards the
center of the alarm. This will deactivate the alarm, stop the
low battery "chirp" and render the alarm safe for disposal
by draining the battery.
